CARE AND MAINTENANCE
Occasional care and maintenance of the unit and the software
are needed to optimize the performance of your unit.
To clean the cabinet
Use a soft and dry cloth.
If the surfaces are extremely dirty, use a soft cloth lightly
moistened with mild detergent solution. Do not use strong
solvents, such as alcohol, benzine or thinner as these could
damage the finish of the unit.
To clean the tape heads
When the tape heads are dirty;
- high frequency sound is not emitted
- the sound is not adequately high
- the sound is off-balance
- the tape cannot be erased
- the tape cannot be recorded on
After every 10 hours of use, clean the tape heads with a head
cleaning cassette.
Refer to the instructions of the cleaning cassette for details.
To demagnetize the tape heads
The tape heads may become magnetized after long-term use.
This may narrow the output range of recorded tapes and increase
noise.
After every 20 to 30 hours of use, demagnetize the tape heads
with a separately sold demagnetizing cassette.
Refer to the instructions of the demagnetizing cassette for details.
Care of discs
• When a disc becomes dirty, wipe the disc from the center out
with a cleaning cloth.
• After playing a disc, store the disc in its case. Do not leave the
disc in places that are hot or humid.
Care of tapes
• Store tapes in their cases after use.
• Do not leave tapes near magnets, motors, television sets, or
any source of magnetism. This will downgrade the sound quality
and cause noise.
• Do not expose tapes to direct sunlight, or leave them in a car
parked in direct sunlight.
